<term>-f <replaceable class="parameter">file</replaceable></term>

<listitem>

<para>

If a <option>file</option> is specified, then the zone is

read from that file to find the DNSKEY records. If not,

then the DNSKEY records for the zone are looked up in the DNS.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-l <replaceable class="parameter">domain</replaceable></term>

<listitem>

<para>

Check for a DLV record in the specified lookaside domain,

instead of checking for a DS record in the zone's parent.

For example, to check for DLV records for "example.com"

in ISC's DLV zone, use:

<command>dnssec-checkds -l dlv.isc.org example.com</command>
